In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

The power handling capability of an output transformer is not constant over the audio frequency range. The lower frequencies require more metal in the core and more windings to provide enough inductance. This means a bigger physical size, …

Audio output transformers are used when load impedances are low, as in line drivers, while audio input transformers are used when load impedances are high, as in line receivers. Output transformers have very low leakage inductance in order to maintain high-frequency bandwidth with capacitive loads.

Audio transformers must utilize both high-permeability cores and the largest practical number of coil turns to create high primary inductance. Coil inductance increases as the square of the number of turns and in direct proportion to the permeability of the core and can be approximated using the formula: L = 3.2 N28 ì A / 10 R
Valve Amps: Output transformers - Lenard Audio

The output transformer is the heart of a valve amplifier. The right pic shows a stereo Leak amplifier. The two output trannys are rotated 90deg to the power mains tranny to avoid picking up induced hum from the mains tranny external magnetic field. Output trannys contribute most of the distortion in a valve amp and have a limited bandwidth.
Audio Transformer, its Types and Impedance Ratio
https://circuitdigest.com/tutorial/audio-transformer
An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is …
Output Transformer Impedance
https://www.radioremembered.org/outimp.htm
The function of the audio output transformer is to transform the high impedance of the output tube to match the much lower impedance of the speaker. This is necessary to get an efficient transfer of the audio signal to the speaker. The output transformer as an impedance matching device, works on the principal of reflected load.
